Application filed January 28, 1919. Serial No. 273,607.

To all whom it may concern:

Be it known that I, WILLIAM R. REED, a citizen of the United States,residing at Baltimore, State of Maryland, have invented certain new anduseful Improvements in GrainConveyers, of which the following is aspecification.

This invention relates to grain conveying devices of harvesting machinesor self binders, whereby the grain is conveyed from the platform to thebinder table. Ord' arily, these devices consist of upper a (1 lowerendless conveyer belts or aprons between which the grain is carried. Thepresent invention has for its object to provide a conveyer structure inwhich the upper apron or canvas is eliminated, whereby the structure issimplified, and also to provide a novel and improved means for directingthe grain onto the lower canvas and assuring the proper forward feed ofthe grain.

The objects stated are attained by means of a novel combination andarrangement of parts to be hereinafter described and claimed, and inorder that the same may be better understood, reference is had to theaccompanying drawings forming a part of this specification.

In the drawings,

Figure 1 is a front elevation of the conveyer mechanism; Fig. 2 is anelevation of said mechanism viewed from the front of the machine; Fig. 3is a longitudinal section of the mechanism, and Fig. 4 is an elevationof the mechanism viewed from the rear of the machine.

Referring specifically to the drawings, 5 denotes a fragment of theplatform of a grain binder across which works the usual slatted conveyerapron 6, the latter carrying the grain to an elevator canvas 7 whichdelivers the grain to the binder table 8. Ordinarily, an upper elevatorcanvas is used in connection with the lower canvas 7, but this uppercanvas has been eliminated, and in its place there is provided a coverplate 9 which is hinged, as shown at 10, to the frame of the elevator,and is held suspended above the canvas 7 by a chain or other suitablesuspension device 11 attached to the seat bar 12 of the machine. Thehinged end of the plate 9 is the upper end of the same, and the chain 11is connected to the lower end of the plate. The plate 9 is thus left iSpecification of Letters Patent.

9 has an upward curve,

free to yield upwardly to prevent grain from clogging between the sameand the canvas 7.

As shown in Fig. 3, the plate 9 is held in spaced and parallel relationto the canvas 7, and it extends from the upper end to within a shortdistance of the lower end of said canvas. The lower end of the plate asshown at 13, so that the grain entrance end of the space between thecanvas 7 and the plate 9 is flared. vThe plate 9 is also located insidethe front guardboard 14: of the elevator.

Above the lower or receiving end of the canvas 7, and beneath the flaredend 13 of the plate 9, is a rotatable grain beater, the same comprisinga drum 15 armed with radially extending fingers 16. This drum hastrunnions 17 and 18, respectively at its ends. The trunnion 17 issupported by a bearing bracket 19 carried by the seat bar 12, and thetrunnion 18 is supported by the board 14.

On the trunnion 18 is a pinion 20 which is in mesh with a pinion 21obtaining motion from the driving means of the canvas 7 Any othersuitable driving means may be provided. The drawings show the pinion 21on a shaft 22 having a sprocket wheel 23 which is driven by the drivechain 24 of the canvas 7. v

Between the adjacent ends of the canvas 7 and the binder table 8 is theusual butt adjuster 25, which, in this instance, is made longer thanusual to extend close to the up per end of the canvas 7.

In operation, the grain is delivered by the platform canvas 6 to thelower end of the canvas 7, and the latter carries the grain to thebinder table 8 as usual. The grain, in passing to the receiving end ofthe canvas 7, comes beneath the beater roller 15 and the fingers 16 ofthe latter assure the proper passage of the grain to the canvas and alsoloosen up the grain and spread it. The grain, as it is carried upwardlyby the canvas 7, is held down on the latter by the plate 9, and as thisplate is free to yield upwardly, clogging of grain is effectuallyprevented.

The device hereinbefore described is very simple in constructions anddevoid of complicated par-ts liable to get out of order, and it can beapplied to existing machines Without alterations in the generalstructure means adjustably and. yieldingly holding thereof.
